Dai is a decentralized cryptocurrency stabilized against the value of the U.S. dollar. Created by the Makers (MKR) Dai Stablecoin System, it uses margin trading to respond to changing market conditions and preserve its value against the major world currencies. Unlike other popular stablecoins whose value is backed directly by USD, it’s backed by crypto collaterals that can be viewed publicly on the Ethereum blockchain.
As of January 2019, Dai can be traded in the following exchanges, including HitBTC, Bitfinex, Coinhub, Coinsuper , Exmo , Radar Relay and many more. DAI is Ethereum ERC20 token and can be stored in ERC-20 compliant wallets like MyEtherWallet, Atomic, Exodus, Jaxx, Mist, Metamask, and others.
